TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES R. EvERsON, of Palmyra, in the county of Wayne, and State of New York, have invented a new and improved Damper for Stove Pipes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical central section of my invention, taken' in the linea: a', g. 2.

Figure 2 is a plan or top view of the same.

Similar letters of reference indicate like parts. t

This invention relates to a neY and improved damper for stove pipes, and it consists in providing a. circular plate hung on journals or pivots, similar to the ordinary damper, with a valvie, and also with a curved or semi` circular 4perforated plate, all arranged in such a manner that when the damper is closed sullcient draught will be allowed to carry o the smoke, gas, etc., which would otherwise escape into the room, and when the damper isiopen the products of combustion be deiected to the side of the pipe-in order that `the heat may be radiated therefrom.

A represents a section of stove pipe in which my improved damper is fitted. B is a circular plate, the diameter of which is somewhat less than the internal diameter of the pipe. This plate, B, is hung on journals, or pivots, a, so that it may turn freely in the pipe, A, and when in a horizontal position and closed, the space,

b, between the edge of the chamber and the stove pipe will afford suiiicient draught to keep the {i1-e alive and` carry off gas, smoke, etc., but admit of a very slow combustion of the fuel in the stove. This plate, B, has a circular concentric opening, c, and C is a circular valve of such diameter that it will cover the opening` c, when in contact with plate B. This valve, C, is provided with two guides, D D, attached to one side of it, which are constructed in loop form, and have a rod, E, passing through them, said rod being attached to plate B,`and extending centrally across the opening, c, as shown clearly in fig. 2. The guides, D D, are of such a length as to admit the valve, C, when at the under side of plate B, dropping suciently low to allow the products of combustion to pass through the opening, c, as shown in black in Iig. 1, and thevalve when in this position is open. When the plate, B, is turned so that the valve will b e on` the Aupper surface of B,.the v-alve willcover the opening, c, and consequently will be closed, as shown in red in iig. 1. The valve, it will be' seen, operates by its own gravity as the plate, B, is turned. E* represents a curved or semicircular plate, which is attached to the side of plate B, extending entirely across the opening, c, and having two openings, d d, made in it, one near each end. This plate, E*, serves as a deiectpr, and when the valve, C, is open throws the products of combustion towards the side of the pipe, A, su that the heat will be radiated into the apartment. (See red arrows, fig. 1.) The device is extremely simple and eicieut, and may be constructed at a small cost.

I am aware that valved dampers operating on the same general principles as mine have before been used, but having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the arched plate E* perforated at 'al d, withthe annular plate B, valve C, loop D, and

shaft E, all constructed and arranged as andfor the purposes specified. t
